对于小学阶段的学生而言,理解并掌握抽象的数学内容,需要直观和情境的支撑。从有意义的情境中获得的课堂知识,学生比较容易习得为可迁移的知识,因为“数学化”的情境为这些知识的运用提供了支撑。创设有效的教学情境,能使课堂教学和谐高效,笔者从以下几方面进行尝试,取得了一些效果:一、聚焦生活,收藏资源。生活处处有数学,作为一个有着良好信息素养的教师就应该注意搜集身边的素材,积累生活中的情 For elementary school students, understanding and mastery of abstract mathematical content requires intuitive and situational support. From the context of the lessons learned from meaningful situations, students are more likely to acquire transferable knowledge because the “mathematical” context provides support for the use of this knowledge. The creation of an effective teaching situation can make the classroom teaching be harmonious and efficient. The author attempts from the following aspects and has achieved some results: First, focusing on life and collecting resources. Everywhere in mathematics, as a teacher with a good information literacy should pay attention to collecting around the material, accumulation of life in love
